Maintenance and warranty

While we have chosen the best components to make this product as rugged and reliable as possible, some parts in audio 
products (potentiometers, faders, switches) are subject to wear which is a matter of operation cycles, and not of time. 
While providing a full time-based warranty according to the country’s of purchase requirements on the function of the 
electronic circuitry, we hence have to limit the warranty on such electro-mechanical parts to 90 days from the date of 
purchase.
In many cases, malfunction of electro-mechanical parts occurs due to dust contamination, which may require cleaning of 
such parts. As the inside of such parts is not accessible, a common practice is to use cleaning fluids in the shape of 
sprays. Please be reminded that many of such fluids contain chemicals which may wash away the dust but at the same 
time corrode or damage contact surface and may cause cosmetic damage to other parts. We hence explicitly exclude 
any claims for exchange of damaged part due to mechanical or chemical impact.
